METHOD FOR MANUFACTURE OF SHEET MATERIAL FOR PRODUCTION OF CANS FOR DRINKS Russian patent published in 2002 - IPC

FIELD: manufacture of sheets of aluminum alloy. SUBSTANCE: the process is conducted in the form of two successions of continuous operations within the line including the continuous hot rolling of a hot aluminum blank within the limits of the first succession for reducing its thickness and rolling-up, and unreeling of the rolled-up blank and hardening to a temperature required for cold rolling within the limits of the second continuous succession of operation within the line; after the continuous hot rolling within the limits of the first continuous succession hardening of the hot blank is accomplished for reduction of its temperature, the cooled-down blank is rolled up, and hardening within the limits of the second continuous succession is accomplished with a preliminary quick heating of the blank for annealing and recrystallization without an intensive precipitation of elements in the form of intermetallic compounds carried out after unreeling of the blank and by a immediate quick cooling of the annealed blank for prevention of precipitation of alloys. EFFECT: improved mouldability of cans from the obtained sheets and enhanced strength. 2 cl, 8 dwg, 3 tbl, 8 ex
